In ancient times, there was a king of Miao Zhuang in the Western Regions. He gave birth to three daughters, named Miao Yin, Miaoyuan and Miaoshan. All three girls are old enough to get married. The eldest girl and the second girl happily got married, but even the third daughter Miaoshan refused to get married and insisted on becoming a monk. King Zhuang was very angry and drove Miaoshan out of the palace. Miao Shan went up the mountain to practice and became an immortal in Xiangshan. Later, Zhuang Wang was seriously ill and dying. As an introduction to medicine, he needs the help of his relatives. Sister and second sister refused to make sacrifices. Only Miao Shan, who became a monk, gave his hand-eye and saved his father's life. Princess Miaoshan's filial piety not only educated King Miao Zhuang, but also touched Sakyamuni's filial piety. In order to help Princess Miaoshan save the suffering beings from time to time, the Buddha gave her 1000 hands and 1000 eyes, making her a Guanyin with thousands of hands and eyes.
